in US format. (Note that there may be an issue if you are searching messages with non-US date formats.) 
the following filter bounces all messages from 

campaign1@yourdomain.com

 that are injected after 

1:00pm on July 28th, 2003:

Do not confuse the 

date

 rule with the 

$Date

 message filter action variable.

The 

header()

 rule checks the message headers for a specific header, which must be specified quoted in 

parentheses (“header name”). This rule may be compared to a regular expression, much like the 

subject

 

rule, or may be used without any comparison, in which case it will be “true” if the header is found in the 
message, and “false” if it is not found. For example, the following example checks to see if the header 

X-Sample

 is found, and if its value contains the string “

sample text

”. If a match is made, the message 

is bounced.

You can specify non-ASCII characters to search for in the value of the header.

The following example demonstrates the header rule without a comparison. In this case, if the header 

X-DeleteMe

 is found, it is removed from the message.
